Enable ruff on Lib/test/test_typing.py

[AlexWaygood]

This removes Lib/test/test_typing.py from the ignorelist we have for ruff. If merged, it means we'll get a helpful CI error if we accidentally have two test methods of the same name in the same class, which leads to one of the two tests being silently skipped.

Locally I was getting this error when running ruff manually (with this PR branch):

>ruff Lib/test
error: Found non-Expr::Tuple argument to PEP 593 Annotation.

I don't know what that means or what's causing it, since there's no line number. But it doesn't seem to be causing any issues in CI 🤷

Minimal reproducer:

from typing import Annotated

Annotated[int]

[hugovk]

Which is from:

    def test_too_few_type_args(self):
        with self.assertRaisesRegex(TypeError, 'at least two arguments'):
            Annotated[int]

I reported this issue on the ruff Discord server (with the help of @hugovk's minimal repro -- thanks!). The issue will go away in the next ruff release (see astral-sh/ruff#7745, which is the fix). So we shouldn't need to worry about this now -- it should be fine to merge this!

I wouldn't be surprised if there's a Ruff release today to support Python 3.12, they just merged a massive PR to support the new f-strings (astral-sh/ruff#7376) and one to declare support (astral-sh/ruff#7713).

Let's wait a little bit and include that in here too.
